%X SiC coated CNTs nano-composites were prepared by the conversion of the precursor polycarbosilane (PCS) and their microstructures were observed and analyzed by SEM, TEM and HRTEM. The electromagnetic parameters of the nano-composites were measured under the frequency from 2 to 18GHZ. Results showed that uniform and compact SiC coatings on the surfaces of CNTs could be synthesized in the initial PCS/xylene concentration section of 10%~15%. The measurement of the electromagnetic parameters of SiC coated CNTs one-dimensional nano-composites indicated that the main electromagnetic loss mechanism was dielectric loss. When the initial PCS concentration was 15%, the SiC coated CNTs nano-composites had the highest dielectric coefficient and loss angle and the best electromagnetic wave absorption properties as well as the composite effects.
